Camera, Flash, and Face ID not working after dropping my IPhone 10 and cracking the back glass.

I dropped my iPhone today and severely cracked the back glass, ok unfortunate right we’ll it’s fine It’s not going to effect the phone. It’s not the front glass and I don’t mind the look of the cracked back glass, looks kinda cool I suppose. Oh but I go to open my phone with Face ID and nope says it’s disabled so I freak out in a panic that I just lost my biometric unlock function that I love on my iPhone I frantically open the camera application and to see a black screen. Well now I have a basically useless phone that I can’t Face ID unlock anymore I cant use my camera I cant use applications that are camera centric such as Snapchat and hey the cherry on top would be I no longer have flash :)…. So hey I keep opening the camera app just to see if it’s going to magically stop freaking out and I take a picture, the camera turns on and the flash works and it took a picture. Cool it fixed right? Nope I restart my iPhone because it still won’t Face ID unlock, thinking it’s fixed I figured it would reset Face ID and my phone would go back to normal. Nope restating it broke it again. Won’t take that picture that reset it, when I do go to take a picture it freezes the phone so I have to turn it off and back on for it to stop it from literally killing itself. I’m turning this into a funny thing but really I just got this phone and its really nice but what the heck I dropped it once and it’s decided it’s done with life. I just need some type of help deciding on what to do next. I don’t think it’s a hardware problem seeing how it like kinda worked for a minute but at the same time I have no clue. I just need an answer or some help fixing this because like I said it’s rendered this phone useless to me and I might have to switch back to my old cruddy iPhone 6 Plus.
